uni of sussex

hey! i’m going to sussex in september n i’m so scared about moving and being able to afford life there. i live in yorkshire rn n from visiting sussex a few times there is a large difference in the price of stuff and accommodation (with it being 8.1k a year in sussex in comparison to 4/5k accom at home). i know there is cheaper accom options off campus n townhouses but i cannot bring myself to share with 11 people and i need to stay on campus as i want to get to know brighton without stressing about travelling to uni everyday if ygm. i understand as brighton is a lovely place n has access to london but it’s so extortionate!
anyway i just wanted to ask is it easy to find jobs in the brighton area and how much money should i save in preparation for moving (i have around 1.6k right now but i know many people go to uni without saving money but i have to or ill stress way too much😞)
but anyway, i’m so excited :3 concerts n everything as nobody decent comes near me n it’s always london. 😡 OH AND ALSO where should i visit when i move bc ive only ever been brighton n eastbourne area n places in between those two, any nice places to go? pls reply i am stressing myself.
